Introduction: Integrating genetic data into conservation management decisions is a challenging task that requires strong partnerships between researchers and managers. Conservation in Latin America is of crucial relevance worldwide given the high biodiversity levels and the presence of hotspots in this region. Methods: We conducted a survey across...

This Report provides a comprehensive, objective, open, transparent, systematic, and rigorous scientific assessment of the state of the Amazon’s ecosystems, current trends, and their implications for the long-term well-being of the region, as well as opportunities and policy relevant options for conservation and sustainable development.

As the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic continues to expand, healthcare resources globally have been spread thin. Now, the disease is rapidly spreading across South America, with deadly consequences in areas with already weakened public health systems. The Amazon region is particularly susceptible to the widespr...

Forests of the Americas and the Caribbean are undergoing rapid change as human populations increase and land use intensifies. We applied the IUCN Red List of Ecosystems (RLE) criteria and simple cost-efficiency analyses to provide the first regional perspective on patterns of relative risk integrated across multiple threats. Based on six indicators...

Genetic research is a well-recognized component of understanding biodiversity and is an invaluable approach for documenting and mitigating increasingly high rates of loss. Here we present a quantitative synthesis of conservation genetics science in Latin America and its progress, focusing on evolving trends on different taxonomic groups, environmen...

La ZDEN-AMO resulta una propuesta o “apuesta” peligrosa y poco pertinente al no contar con instituciones sólidas que garanticen el debido proceder y la continua supervisión con el fin de evitar y mitigar los impactos a nuestra biodiversidad y procesos ecológicos en un área particularmente susceptible, con poca capacidad de recuperación, como la Ama...

Knowledge products comprise assessments of authoritative information supported by standards , governance, quality control, data, tools, and capacity building mechanisms.

Unique visitors per year to knowledge products’ websites. (DOCX)

Calculation of the cost of achieving pre-defined baselines by 2020. All extrapolations were derived through data from the sample compiled in the study and projections provided by each knowledge product team. (DOCX)

Currency conversions and accounting for inflation. Costs were provided in British Pounds (GBP), US Dollars (US$), Euros (EUR), Australian Dollars (AUD), and Swiss Francs (CHF) of the year when the investment took place. We accounted for inflation by calculating the value of the currency in 2014 and then we transformed all currencies to US Dollars (...

Extrapolated one-off costs costs per funding source between 1979 and 2013 for all four knowledge products. Extrapolated one-off costs costs per cost categories between 1979 and 2013 for all four knowledge products. (DOCX)

Summary of data collection for all four knowledge products. The table summarises which costs were collected for each of the four knowledge products and how much of the total number of assesments, available in December 2013, these represent. In cases where 100% of the costs were not collected, the total sum for each knowledge product was increased p...

Deforestación en la Amazonía (1970-2013) es el título de este estudio, que analiza las tendencias históricas y recientes de la deforestación ocurrida en todos los países de la región amazónica. El análisis establece que la deforestación acumulada al 2013 corresponde al 13,3% de la cobertura boscosa original de la Amazonía, y estima que la mayor pér...

In response to growing demand for ecosystem-level risk assessment in biodiversity conservation, and rapid proliferation of locally tailored protocols, the IUCN recently endorsed new Red List criteria as a global standard for ecosystem risk assessment. Four qualities were sought in the design of the IUCN criteria: generality; precision; realism; and...

The newly developed IUCN Red List of Ecosystems is part of a growing toolbox for assessing risks to biodiversity, which addresses ecosystems and their functioning. The Red List of Ecosystems standard allows systematic assessment of all freshwater, marine, terrestrial and subterranean ecosystem types in terms of their global risk of collapse. In add...

Carbon sequestration is a widely acknowledged and increasingly valued function of tropical forest ecosystems; however, until recently, the information needed to assess the carbon storage capacity of Amazonian indigenous territories (ITs) and protected natural areas (PNAs) in a global context remained either lacking or out of reach. Here, as part of...

“Chaguaramales” are palm swamp forest formations dominated by Roystonea oleracea (Palmae). Situated in northeastern Venezuela they are little known communities, exhibiting a high level of human disturbance. To collect information required for their conservation and restoration management, studies were conducted in selected locations of the Aroa Riv...

Current scientific capacities in Austral and Neotropical America (ANA) for plant conservation genetics (PGC) were assessed. Publications (1980–2010) were analyzed, considering the taxa and geographical origin of samples, geographical origin of the institutional affiliation of the authors (first, corresponding and co-authors), the threat category of...

An understanding of risks to biodiversity is needed for planning action to slow current rates of decline and secure ecosystem services for future human use. Although the IUCN Red List criteria provide an effective assessment protocol for species, a standard global assessment of risks to higher levels of biodiversity is currently limited. In 2008, I...

Background / Purpose: Building on the success of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species, the IUCN recently launched the development of the Red List of Ecosystems (1). In the first major test of this system, we applied proposed categories and criteria to the terrestrial ecosystems of Venezuela. Ma...

To characterize the commercial trade of medicinal plants in Caracas, Venezuela, five popular markets and 10 herb stalls were visited. Stall keepers were interviewed to determine which species were being sold and which were their traditional uses. One hundred ninety eight samples were recorded and 164 species from 72 families were identified. Most o...

Topical literature and Web site databases provide genome sizes for ∼4,000 animal species, invertebrates and vertebrates, 330 of which are mammals. We provide the genome size for 67 mammalian species, including 51 never reported before. Knowledge of genome size facilitates sequencing projects. The data presented here encompassed 5 Metatheria (order...

According to estimates of the World Health Organization more than 80 per cent of the world population uses traditional medicinal plants to provide primary health care, particularly in developing countries. However, in such countries traditional knowledge regarding the use of medicinal plants has been significantly lost. Moreover, the availability o...

Las plantas constituyen un recurso valioso en los sistemas de salud de los países en desarrollo. Aunque no existen datos precisos para evaluar la extensión del uso global de plantas medicinales, la Organización Mundial de la Salud (OMS) ha estimado que más del 80% de la población mundial utiliza, rutinariamente, la medicina tradicional para satisfa...

Seventeen species of bats of Venezuelan highland forest, pertaining to three families (Phyllostomidae, Mormoopidae, and Vespertilionidae) were considered for genome size (g.s.) evaluation. Feulgen stained lymphocytes were microdensitometrically evaluated from two blood smears for each individual. The g.s. we got range from 4.5 pg forLonchorhina aur...
